Intervene
Source
Character Operations Manual pg. 55
As a reaction when an adjacent ally would be damaged by an attack, you can take half the attack’s damage, with your ally taking the remaining damage. This doesn’t prevent your ally from suffering related effects, nor does it cause such effects to apply to you. If you have the Bodyguard feat and you take a reaction to apply that feat’s benefit to an adjacent ally who is then hit by the attack, you can activate intervene for that attack without taking an additional action.
